The world’s best paper machine: UWF speed record of 1,808 m/min

Jul 2, 2013

On September 1, 2011, the world's largest and fastest woodfree-producing paper machine was started-up at the Zhanjiang Chenming mill in China. During its first operational year, it achieved on several occasions a new world speed record. In November 2012, the recorded speed was 1,808 m/min. During a 24-hour run, the 11.15-meter-wide PM 1 produced high quality printing paper at a basis weight of 70 g/m2.

Planning a grade conversion?

The world is changing fast; the consumption of newsprint and printing paper is decreasing and the consumption of containerboards or cartonboards are increasing. An old paper machine can be updated with a grade conversion rebuild to produce more profitable products. Turn a new page for your paper machine with the help from Valmet.
